SRG-APP-000516-DNS-000095
Group -
Primary authoritative name servers must be configured to only receive zone transfer requests from specified secondary name servers.
Authoritative name servers (especially primary name servers) should be configured with an allow-transfer access control substatement designating the list of hosts from which zone transfer requests ...Rule Medium Severity -
SRG-APP-000001-DNS-000115
Group -
The Infoblox system must limit the number of concurrent client connections to the number of allowed dynamic update clients.
Limiting the number of concurrent sessions reduces the risk of Denial of Service (DoS) to the DNS implementation. Name servers do not have direct user connections but accept client connections for...Rule Medium Severity -
SRG-APP-000125-DNS-000012
Group -
The Infoblox system audit records must be backed up at least every seven days onto a different system or system component than the system or component being audited.
Protection of log data includes assuring log data is not accidentally lost or deleted. Backing up audit records to a different system or onto separate media than the system being audited on a defin...Rule Medium Severity -
SRG-APP-000142-DNS-000014
Group -
Infoblox systems configured to run the DNS service must be configured to prohibit or restrict unapproved ports and protocols.
In order to prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable...Rule Medium Severity -
SRG-APP-000158-DNS-000015
Group -
Infoblox systems which are configured to perform zone transfers to non-Grid name servers must utilize transaction signatures (TSIG).
Without identifying devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. This applies to server-to-server (zone transfer) transactions only and is pr...Rule Medium Severity -
SRG-APP-000176-DNS-000094
Group -
Only the private key corresponding to the ZSK alone must be kept on the name server that does support dynamic updates.
Infoblox systems when deployed in a Grid configuration store DNSSEC keys on the designated Grid Master system. As the central point of administration, the Grid Master should be configured for admin...Rule Medium Severity -
SRG-APP-000176-DNS-000096
Group -
Signature generation using the KSK must be done off-line, using the KSK-private stored off-line.
Infoblox systems when deployed in a Grid configuration store DNSSEC keys on the designated Grid Master system. As the central point of administration, the Grid Master should be configured for admin...Rule Medium Severity -
SRG-APP-000185-DNS-000021
Group -
The Infoblox system must be configured to employ strong authenticators in the establishment of nonlocal maintenance and diagnostic sessions.
If maintenance tools are used by unauthorized personnel, they may accidentally or intentionally damage or compromise the system. The act of managing systems and applications includes the ability to...Rule Medium Severity -
SRG-APP-000213-DNS-000024
Group -
The Infoblox system must be configured to provide additional data origin artifacts along with the authoritative data the system returns in response to external name/address resolution queries.
The underlying feature in the major threat associated with DNS query/response (i.e., forged response or response failure) is the integrity of DNS data returned in the response. The security objecti...Rule Medium Severity -
SRG-APP-000214-DNS-000025
Group -
A DNS server implementation must provide the means to indicate the security status of child zones.
If name server replies are invalid or cannot be validated, many networking functions and communication would be adversely affected. With DNS, the presence of Delegation Signer (DS) records associat...Rule Medium Severity

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
